Focusing on the cause and impacts of light pollution (2017-18)
|Project title||Focusing on the cause and impacts of light pollution|
|Approved budget (HKD)||100,000|
This project aims to (1) promote good lighting practice by creating an online public directory of good and poor lighting installment in the communities, focusing on all aspects of the light, including intensity, light trespass, and the spectral energy distribution; (2) promote and establish the impact of the project in the local astronomy community; (3) continue our successful international knowledge exchange effort through the Globe at Night – Sky Brightness Monitoring Network project which adopt the HKU-developed standardized method of quantifying the extent of light pollution.
- To promote good practice of lighting in Hong Kong which minimize light pollution
- To characterize the composition of light of the common lighting sources in Hong Kong, an important characteristic in determining the amount of light pollution
- To establish evidence of impact on the local amateur astronomical community
- To promote the light pollution measurement technique developed by HKU and the results from the ongoing HKU’s international light pollution study to the public.
